There are some languages that are better than others and more eloquent than others. There are some languages that you can explain something in a lot of ways also in a very elegant way, A good example is the Arabic language. But every language is beautiful in its own way.
All languages are equal because they represent people, Culture, And history. Eliminating less superior language is just another form of discrimination or culture superiority. That would just lead to more chaos and we really do not need that you know? So lets not call languages superior above the other languages.
